I was catching limits everytime till water warmed up. First time water was 65 then 69 once it got to 70 catch rate started dropping. Yesterday water was 81 we had 10 in the boat by 1pm,we changed tactics and spider rig along the shoreline in 8 to 10 ft. of water and ended up catching 25 more in 2Hr. The only thing I can think of is we had a storm the night before and it moved them to cover. Any other ideas? I always thought the cranks work better the hotter the water got.
